Definitions

  • the present invention relates to a circular knitted fabric which has a 1 ⁇ 1 rib jacquard knitted structure as a basic structure and is plate-knitted by non-elastic fiber yarn and elastic fiber yarn.
  • a circular knitted fabric using elastic yarn has conventionally been known.
  • a circular knitted fabric is known in which in rib knitting (fraise knitting), interknitting is performed such that cotton yarn or synthetic fiber-blended yarn, and covered elastic yarn are lined up alternately through knitting, and then a moisturizing property, hygroscopicity, and a moderate fitting property are provided.
  • the elasticity in the course direction (a horizontal direction, that is, a cylinder circumferential direction) is larger than that in the wale direction (a vertical direction, that is, a cylinder axial direction).
  • the elasticity in the course direction where elasticity is originally excellent is further increased.
  • the elasticity in the wale direction does not increase so much, and thus the balance in elongation between the wale direction and the course direction is not good.
  • Patent Literatures 1 to 3 attempts to increase the elasticity in the wale direction and the course direction have been made.
  • elastic yarn is used for some loops, and the loops are continuous in the wale direction. Therefore, elasticity occurs between courses to which elastic yarn has been fed so that elasticity in the wale direction also increases. As a whole, elasticity in three directions of the wale direction, the course direction, and the diagonal direction increases.
  • an object of the present invention is to provide a circular knitted fabric that is good in balance of elongation between a wale direction and a course direction and has a knitted pattern, and a method of manufacturing the same.
  • the circular knitted fabric of the present invention is a circular knitted fabric having a 1 ⁇ 1 rib jacquard knitted structure as a basic structure.
  • non-elastic fiber yarn and elastic fiber yarn are fed as a full set and are plate-knitted.
  • Knit-loops account for 10 to 90% of all structures, and at least any one of a tuck and a welt is included so that a knitted pattern is formed on a knitted fabric surface due to a difference between structures by location.
  • Elongation in each of a wale direction and a course direction is 100 to 280% under a load condition of 14.7 N/2.54 cm, and an elongation ratio, that is, (elongation in wale direction)/(elongation in course direction), is 0.5 to 2.0 under the load condition of 14.7 N/2.54 cm.
  • a finished knitting density is 105 courses or more/2.54 cm and 48 wales or more /2.54 cm.
  • fineness of the elastic fiber yarn is 11 to 110 dtex
  • fineness of the non-elastic fiber yarn is 11 to 110 dtex
  • the fineness of the elastic fiber yarn:the fineness of the non-elastic fiber yarn is 1:0.3 to 1:4.5.
  • a method of manufacturing the circular knitted fabric of the present invention is a method of manufacturing a circular knitted fabric in which a 1 ⁇ 1 rib jacquard knitted structure is knitted as a basic structure, in which non-elastic fiber yarn and elastic fiber yarn are fed as a full set and plate-knitted. Knit-loops account for 10 to 90% of all structures, and at least any one of a tuck and a welt is formed so that a knitted pattern is formed on a knitted fabric surface due to a difference between structures by location. In feeding each of the non-elastic fiber yarn and the elastic fiber yarn, while tension of yarn to be supplied is monitored, an amount of fed yarns is adjusted such that the tension is kept constant.
  • the circular knitted fabric of the present invention is obtained by plate-knitting elastic fiber yarn fed as a full set, and has the above-described elongation and elongation ratio.
  • the elongation in the wale direction and the course direction is high, and the balance in elongation between both directions is good.
  • the circular knitted fabric of the present invention in addition to a knit-loop, at least any one of a tuck and a welt is included.
  • a knit-loop in addition to a knit-loop, at least any one of a tuck and a welt is included.
  • the surface is uniform in a portion with a high ratio of knit-loops, whereas a transparency feeling occurs and a change occurs on the surface in a portion with a low ratio of knit-loops. Therefore, the ratio of knit-loops is arbitrarily changed depending on locations, so that the circular knitted fabric has an excellent design with a change on the surface.
  • knit-loops account for 10 to 90% of all structures, and the rest is occupied by characteristic portions by tucks and welts.
  • the circular knitted fabric is stabilized and the degree of freedom of the knitted pattern is high.
  • the circular knitted fabric of the present invention since non-elastic fiber yarn and elastic fiber yarn are fed as a full set and are plate-knitted, it is possible to manufacture the circular knitted fabric that is good in balance of elongation between a wale direction and a course direction. Also, since in addition to a knit-loop, at least any one of a tuck and a welt is formed, it is possible to manufacture the circular knitted fabric having various knitted patterns according to a difference in the structure. Then, in feeding each of the non-elastic fiber yarn and the elastic fiber yarn, while tension of yarn to be supplied is monitored, an amount of fed yarns is adjusted such that the tension is kept constant. Thus, the knit-loop, the tuck and the welt may be freely formed.

  • the 1 ⁇ 1 rib jacquard knitted structure is composed of front-back ground structures in two layers.
  • yarns in the ground structures are entwined with each other and connected, and connecting yarn that connects the ground structures in the two layers is not used. Since no connecting yarn is used, the elongation of the circular knitted fabric is hardly impaired, and knitting is easy, and also a problem such as displacement of the ground structures in the two layers also hardly occurs.
  • the circular knitted fabric of the embodiment is plate-knitted (also referred to as plating yarn-knitting) in which non-elastic fiber yarn and elastic fiber yarn are fed as a full set.

Therefore, the elastic fiber yarns are continuously lined up in the wale direction and the course direction, and the elongation of the circular knitted fabric in both directions increases.
